Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional perforation tools are used, then explosive charges can be delivered to the well site, but the tools are cumbersome to transport and require separate transport of explosive assemblies
Solution Approach 1:
The patent combines the initiator module and explosive charge assembly into a single integrated perforation tool that can be transported as one unit. The initiator module is positioned within the same housing as the explosive charges, eliminating the need for separate transport of explosive assemblies while maintaining safety through the bulkhead separation.
Solution Approach 2:
The perforation tool is divided into modular segments including the initiator module, bulkhead member, and charge assembly that can be independently manufactured and then assembled. This segmentation allows for easier manufacturing and transport of individual components while maintaining the integrated functionality of the complete tool.
2Adaptability or versatility
If shaped charges are secured in fixed positions in the perforating gun, then the charges are stable, but flexibility in applying the blast is restricted
Solution Approach 1:
The liner assembly includes movable components that allow the shaped charges to be positioned at different angles and orientations within the perforation tool. The liner can be rotated or adjusted to direct the blast in desired directions, providing dynamic positioning capability while maintaining secure attachment during transport and operation.
